Pediculosis Pubis

Pediculosis pubis is caused by Phthirus pubis (diptera: anoplura) commonly known as crab louse, an obligatory ectoparasite, found on human hair and requires human blood to survive. Pubic lice can be found on pubic hair, underarms, thigh and leg hair, beard and rarely on eyebrows and eyelashes. They are rarely found on scalp hair. Spread of lice occurs mostly by sexual contact but spread via non-sexual contact although rare has also been reported. I present the case of a middle-aged woman with pubic lice. No lice/nits were found in underarm hair, eyebrows or eyelashes. A review of literature is enclosed.

Abstract The use of hair as an index to the concentration of certain elements in tissues has been evaluated with regard to the effect of prior cosmetic and sample-washing treatments on the results. Untreated rat-hair samples were subjected to selected grooming or cosmetic products and then washed by various commonly cited sample-preparation procedures. The hair samples were then analyzed for Ca, Mg, Cu, and Zn, and the concentrations found were compared to those in untreated samples. The results indicate that the values observed can be greatly altered by typical treatments given to human hair, and that such changes are not corrected by the commonly used sample-wash procedures. Thus, obtainable samples of human hair, including pubic hair, cannot be expected to indicate accurately the concentration of these metals that would otherwise be present. Other elements should be similarly studied before confidence can be placed in the validity of data for them.

Scanning Electron

Using standard techniques of scanning electron microscopy (SEM), over 1000 human hair defects have been studied. In several of the defects, the pathogenesis of the abnormality has been clarified using these techniques. It is the purpose of this paper to present several distinct morphologic abnormalities of hair and to discuss their pathogenesis as elucidated through techniques of scanning electron microscopy.

Extracellular Materials

Ruthenium red has been used as a stain to demonstrate a variety of extracellular materials, especially acid mucopolysaccharides. It also reacts with certain intracellular and extracellular lipids. Since biochemical studies in our laboratory demonstrated the presence of a variety of monosaccharides in human hair ruthenium red staining procedures were adopted in order to evaluate the presence and morphological location of acid oligosaccharides in the keratinized aspect of hair.

The purpose of this study was to examine the external structure of four human hair shaft samples with the scanning Electron Microscope (SEM) and to obtain information regarding the chemical composition of hair by using the attached x ray microanalysis unit.The hair samples were obtained from two female subjects. Sample A was taken from a black female and had not undergone any type of chemical processing. Sample B, C, D were taken from a white female, and were natural, processed, and unpigmented, i.e. “gray”, respectively. Sample C had been bleached, tinted, and chemically altered using a permanent wave technique.

Sem Study

High school cosmetology students study the methods and effects of various human hair treatments, including permanents, straightening, conditioning, coloring and cutting. Although they are provided with textbook examples of overtreatment and numerous hair disorders and diseases, a view of an individual hair at the high resolution offered by an SEM provides convincing evidence of the hair‘s altered structure. Magnifications up to 2000X provide dramatic differences in perspective. A good quality classroom optical microscope can be very informative at lower resolutions.Students in a cosmetology class are initially split into two groups. One group is taught basic controls on the SEM (focus, magnification, brightness, contrast, specimen X, Y, and Z axis movements). A healthy, untreated piece of hair is initially examined on the SEM The second group cements a piece of their own hair on a stub. The samples are dryed quickly using heat or vacuum while the groups trade places and activities.
